New Scenery Install

Hi,

I noted that new scenery has sometimes instructions to be installed in the ad-on scenery folder and sometimes directly to the scenery folder. Is there any difference? I actually have an ad-on airport installed PRG (LKPR), as directed have installed it to ad-on scenery and when opening LKPR and adjusting some gates through AFCAD the change does not happen?

Any help would be welcomed
Thanks

As you say, different scenery has to be installed in different ways.
Always follow the read-me that comes with the download or it won't work.

Thanks,
I am aware of this. But have noted that some ad-on airports scenery cannot be changed by AFCAD and some can, so thought that the location of it (Scenery or Ad-on scenery) could have affect.
